G400 screen corruption

[Paddy]

I have noticed that sometimes i get a vertical line about 4/5 of the way across the monitor (from the left).
The line is a greyish colour and only appears i think in certain resolutions when using OGL.

I first noticed this on the demo sequence for Unreal Tornament and i put it down to a dodgey driver or the game. But i have noticed this in other apps now such as Winamp plugins.

As it is so far limited to these two progs i am not that bothered and i am still inclined to think it is a software problem - please tell me otherwise. (or dont!)

Cheers,
Patrick

Hi,

I similarly have this problem. This vertical light and dark bands occurred about 2/3 to 4/5 of the screen from the left. It moved a little depending on resolution and refresh rate. When I changed the VGA cable to the BNC cable -- the light band (or light grey vertical line) improved drastically, and is now just 1 cm from the left edge of the screen. It is present in all resolution and all application -- at refresh rate of 60Hz it is much improved. It is most obvious when the background is uniformly grey.

Anyone out there with a solution ?

My hardware config :-
My system configuration is as follows :-
PIII 667 BE (coppermine)
SD133 128 mb Mitsubishi ram on board
Microstar BX-Master motherboard
Sony 19' GDM F400 monitor - 1600x1200 85Hz 32bit colour
Window Media Player v6.4
DirectX 7.0a
G400 Max driver ranging from 5.1 to 5.5 (all version sharing this problem)

Thanks

Are you talking about a single row of pixels or a more blurry vertical region?

[Paddy]

It is a more blurry vertical region

I have seen a similar problem with both my old TNT and G400, but for me it seems to be more of a slight variation in color which is only noticable on a somewhat dark uniform color filling the screen. It occurs along a roughly 5mm wide vertical area that changes in position slightly with resolution. It is probably either an imperfection in the monitor or perhaps a result of some other device causing interference.

I agree with the comment Fyx, It only appears on dark backgrounds. Although Unreal and this bloody winamp skin is the only thing i have noticed it on. I have not noticed that it changes position with resolution changes.

Can anyone else confirm that it is my monitor and not the card or a driver prob?

It's a monitor thing, in fact, most if not all monitors and tv's have that "prob".

[Paddy]

Cheers everyone!
I guess i dont have to return my card

Are you guys useing apriture grill monitors (trinitron, Dimondtron, etc)?. If so you will never get rid of it. It is a bar (actually two bars) that support the grill. It can also be seen on trinitron TVs but is less noticable as it's in less demanding, critical use.

One is about a third of the way down from the top, the other about a third up from the bottom; they devide the screen into thirds.

Most people either get used to it (most), or give up on apriture grill monitors and get CRTs (less). Heck I guess today some might even switch to LCDs, who knows.

Just remember if you have a trinitron based monitor, nothing is 'wrong'. It's just a shadow.

Those are horizontal, not vertical.
